Starting the allsky software at specific times only
Is there a way to start the allsky software only at sunset and making it stop at sunrise .

Thank you
Claude

To tell it not to take pictures during the day, you can use the GUI -
Editor --> Config.sh: DAYTIME_CAPTURE="false"
Camera Settings --> Other Settings --> Angle: 0 starts right at sunset.
That'll tell it not to capture during the day, but the software will be running in the background.

If you're after power-savings, fully stop & start it, maybe sudo crontab -e.. (idea from this link)
I'm not 100% sure if this will work without the full path to sunwait, just not sure where it's installed on this current release.
Put in your LAT & LON in the appropriate spots in the example below.
0 3 * * * sunwait wait sunrise 53.569116N -1.661271E; service allsky stop
0 15 * * * sunwait wait sunset 53.569116N -1.661271E; service allsky start

I've had mixed results using CRONTAB & SUNWAIT, so if you go that route, i hope this will work for you :)

@jcauthen78 Jim, That's save almost no CPU. When not capturing during the day, Allsky determines how long till nighttime, then sleeps that long. So it's taking no CPU for 99.9% of the daytime.

@cboivin11 The Wiki has a page dedicated to answering your question. It's called something "**Angle & sunrise/sunset". Most questions you'll have are already answered in the Wiki, if a fair amount of detail.

Hi I did not explain what I want correctly� I want to start the allsky software a sunset and stop at sunrise after the timelapse is done� The start and end of capture is well understood and works ok Merci et bonne journée Claude Boivin De : Jim ***@***.***> Envoyé : 5 août 2022 12:27 À : thomasjacquin/allsky ***@***.***> Cc : cboivin11 ***@***.***>; Author ***@***.***> Objet : Re: [thomasjacquin/allsky] Starting the allsky software at specific times only (Discussion #1487) To tell it not to take pictures during the day, you can use the GUI - Editor --> Config.sh: DAYTIME_CAPTURE="false" Camera Settings --> Other Settings --> Angle: 0 starts right at sunset.

@cboivin11 Claude, Allsky doesn't have a mechanism to start and stop itself so you'd need a cron job or something similar. It would be much easier to simply turn off daytime capture. Allsky will then put itself to sleep during the day so take almost no CPU time.

If you use a cron job, it will need to take into account how long after nighttime ends that it takes to create the startrails, keogram, and timelapse video, since stopping allsky while they are running stops them as well.
